MOBILITY IMPACTS OF LINE 1 OF THE METRO OF NAPLES: THE CASE STUDY OF GARIBALDI STATION

In this paper the focus will be on the area surrounding Garibaldi square in Naples in Italy following the inauguration of the station Garibaldi of Line 1 of the metro in January 2014. Indeed, many interventions of different types have been carried out, with a subsequent reconfiguration of the whole transport system connecting this node. Private and public transport needed to be reorganized after the inauguration of the new station with the objective of making mobility efficient as a function of the transport demand on the network. In order to evaluate both transport demand and supply, it has been necessary to undertake two surveys: the first one aimed at identifying the present circulation scheme and the one induced by the inauguration of the station. The second one aimed at quantifying the entity of traffic flows in "critical points", by counting the vehicles during peak periods. From the surveys, it has come out that in the peak morning period (7am -10am) 6,000 vehicles have been counted towards the rail node Garibaldi. This value decreases of almost 15% in the afternoon peak period (12 am - 3 pm) as well as in the evening one (5pm -8pm). From the simulation of the future scenario, which changes radically the access to Garibaldi Square and to the surrounding areas (where the CBD and the historical centre are placed), a new distribution of the vehicles is registered with a decrease of flows coming from the motorway A3 of more than 20% and of more than 30% approaching Garibaldi square. The implemented model is also able to assess future scenarios promoted by the local administration.
